SPECIFICATION forming part of Letters Patent No. 742,439, dated October27, 1903.

I Applioationfiled April 28, 1902. Serial No. 105,031. (No model.)

To all whom it may concern:

Be it known that LFRANK LESLIE J oHNsoN, a subject of the King ofEngland, residing at Sapperton, in the Province of British Columbia, inthe Dominion of Canada, have invented certain new and usefulImprovements in Shingle-Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates particularly to shin-.-

gle-machines wherein the saw is rotated in an upright position.

This invention has for its object the provision of means by whichshingles may be more expeditiously cut from the block and jointed readyfor packing into bunches.

A further object of the invention is to provide improved means wherebythe set-up of the block may be controlled so as to more nicely regulatethe thickness of both butts and points of the shingles.

A still further object of the invention is the provision of features ofconstruction pertaining to the carriage travel or feed whereby themotion imparted to the carriage is better adapted to its work than inany other shingle-machine which has come to my notice.

The invention consists in the novel construction and combination ofparts hereinafter described, illustrated in the drawings, and finallypointed out in the claims.

In the said drawings, Figure 1 is a front elevation of a shingle-machineembodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 isa cross-section through line w a; of Fig. 2. Fig. 4 is an elevation of aportion of the machine looking in the direction of arrows shown in Fig.2. Figs. 5 and 6 are detail views of the lower end of the blockcarriage.

In the drawings the numeral 2 designates the main frame; 3 3, standards,the former,3,

being secured to the main frame and connected to the other, 3, which isseated upon the floor, by two horizontal girders 4 4: provided,respectively, upon their top and bottom faces with planed carriagetracks or ways 5 5.

The shingle-saw 6 is secured by counter sunk screw-bolts to its collar7, which is bolted to the flange 7' of arbor 8, journaled in babbittedboxes 9, adjustably secured by setbolts 9 and lock-bolts 9 to pedestals10 of frame 2. I Mounted upon the said saw-arbor are pulleys 11 12, theformer, 11, being the arbor drive-pulley, and 12 for operating thecarriage feed-works,'to be hereinafter described.

The carriage consists of upright ends 13 13", bottom or bed piece 14,and top piece 15, rigidly secured together. The top piece 15 ischanneled and babbitted at its opposite ends .15, so as to make aslidable fit with its track 5 of preferably rectangular cross-section.The bed-piece 14 is chambered adjacent to its ends'for the reception ofannularly-grooved wheels 20,which run on V-track 5. The axles of saidwheels are seated in babbitted halfboxes 16, which are communicativelyconnected through holes 16 to oil-wells 16, in each of which is placedan absorbent material, such as felt, that will exude oil to the journalsof said axles when raised to a high temperature. A thrust-plate 17,seated in one end of each of the said axles, and setscrews 17 areprovided for transverse adj ustment of the axles of the carriage-wheelsto compensate for the wear of the same. Ad-

. jacent to ends of said bed-piece of the carriage, journal-boxes 18 areprovided for a roller-shaft 19, having a plurality of spurwheels 19fixedly mounted thereon. Integral with the bed-piece is a jaw 21, havinga number of teeth 21 disposed so as to receive the block spalt after ithas run off of the spur-wheels 19. A swinging frame 22, pivotallyconnected by arms 22' to the end pieces 13 13' of the carriage, isutilized for supporting another toothed jaw, 23, by a swivelpin 23intermediate of its length, 'so as to permit the said j aw to be tiltedlongitudinally of its length to accommodate blocks with ends out ofparallel. A weight 24:, attached to lever 24:, fulcrumed at 24 to abracket 25 on the top frame-girder and a link 25, keeps the jaw seatedupon the block, and supplemental means for exertinglocal pressure uponthe block is obtained by a compression-spring 26, introduced between abracket 26 and the top of the jaw 21, adjacent to the end thereof.Another roller-shaft, 27, with fixedspurwheels 27, is seated injournal-boxes provided at the ends of the swinging jaw, and consequentlyis tilted coincidently there- IOO with. Mounted upon an end of each ofthe said roller-shafts is a pair of ratchet-wheels 28, one of each pairbeing fixed to its shaft and the other one being adjustably securedthereto for regulating, in connection with the cam hereinafterdescribed, the thickness of the shingle cuts, both of points and butts.The roller-shafts are rotated step by step, so to speak, by means ofpawls 29, connected by pawl-arms 29 to a vibrating lever 30 atequidistant points from its fulcrum 30. The vibratory motion of saidlever is accomplished by means of a wheel 30 upon its upper extremitytraveling in a channel-way 31, extending parallel to and along the topframe-girder until it reaches part 32 regis tering therewith, but freeto be swung horizontally to vary the offset or vibration of theratchet-lever. 33 represents stud-bolts passing through slots 34 of thelast-named part 32 for securing the same to a set position.

Returning now to the carriage-feed, a pitman 35 connects the carriage toa rocking le-.

ver 36, actuated by sliding crank-box 36, journaled to crank-pin 37 ofdisk 37. The fulcrum of said rocking lever is a pin 36", suspended fromthe main frame and positioned at one side of a vertical line passingthrough the axis of shaft of said disk, but opposite to the shingle-saw,thereby imparting slow feed with a quick return motion to the carriage.Rotary motion to the said disk is obtained through shaft 38 from a beltpassing around pulley 38 thereon and 12 on the saw-arbor by frictionalcontact of a paper pulley 40 with an iron pulley 41 on shaft 41 andthence through toothed pinion 42 and internal gear-wheel 43 on thedisk-shaft 44. Shafts 41 and 44 are journaled in stationary bearings;but shaft 38 is journaled in eccentricbox 45, whereby the frictionalgear of the feed mechanism is thrown into or out of operation. Theeccentric-box is operated by lever 45, integral therewith, a toggle 46,shaft 47, connected by lever 47, mounted thereon, to said toggle,another shaft, 48, arm 48 thereon, and link 49, connecting said arm withan arm 50 upon shaft 47. A hand-lever 51 and foot-treadle 52 areprovided upon the shaft for controlling the feed mechanism from eitherthe end or front of the machine, as desired. The toggle 46 and itsactuatinglever are arranged so that when the foottreadle is depressedthey will be in line and lock the eccentric-box; but when moved out of aright line by the hand-lever a counterweight 53, attached to an arm ofeccentriclever, rotates the eccentric to throw the aforesaid paper andiron friction-wheels into ongagement.

Ashingle-jointerisincluded in the machine and comprises a jointer-saw 54and its arbor 55, disposed rectangularly to the aforesaid shingle-sawarbor and journaled in boxes 56, vertically adjustable by means of slots57 in the said box-castings and screw-bolts 58. A bracket 59 supports aplate 60, to which is secured another (wedge-shaped) plate, 61, beveledupon its top surface for tilting the shingles forward as they drop fromthe shingleblock. The bolts 62 are provided for moving inwardly as thesaw is worn. A table 63, hinged at 63 to the machine, is used forbolding the shingles while jointing, which is accomplished by placingthe same thereon and pressing downward against the action of anextensible spring 64; the shingle edges coming in the path of thejointer-saw cuts and trims the same. I
